4 Claims. (Cl. 20-49) I This invention relates to improvements in a window mounting and more particularly to a horizontally pivoted window mounting.

An object of the present invention is to provide a window mounting having structural simplicity, being economical to manufacture, being easy to assemble, being of strong and sturdy nature, having operating efficiency, and having a long wear life.

Other features of this invention reside in the arrangement and design of the parts for carrying out their appropriate functions.

Other objects and advantages of this invention will be apparent from the accompanying drawings and description and the essential features will be set forth in the appended claims.

In the drawings,

Fig. l is an outside view of a window frame mounted in a building wall and having two window sashes therein;

Fig. 2 is a vertical sectional view, taken along the line 2-2 of Fig. 1, showing the horizontally pivotal action of the lower window sash about its transverse axis in the different dot-dash and solid line positions;

Fig. 3 is an enlarged horizontal sectional view through oneside of the window sash and window frame taken along line 3-3 in the solid line position of Fig. 2;

Fig. 4 is a vertical sectional view through the window frame and window sash taken along the line 44 of Fig. 3;

Fig. 5 is a vertical view along the line 5-5 of Fig. 3 looking toward the window mounting strip member but with the window sash and sash strip removed; while Fig. 6 is a vertical view taken along the line 6--6 of Fig. 3 along the same line as Fig. 5 but looking in the .opposite direction toward the window sash and sash strip.

Before the window mounting here illustrated is specifically described, it is to be understood that the invention here involved is not limited to the structural details or arrangement of parts here shown since window mountings embodying the .present invention may take various forms. It also is to be understood that the phraseology or terminology herein employed is for purposes of description and not of limitation since the scope of the present invention is denoted by the appended claims.

Those familiar with this art will recognize that this invention may be applied in many ways, but it has been chosen to illustrate the same in connection with a window sash pivotally mounted on a horizontal axis in a window frame. This invention is especially intended for use when both the window sash and window frame are made of metal for long life and durability. The window sash is not only horizontally pivoted but also can travel vertically within the window frame. This structure permits the window pane in the window sash to be washed on both sides and permits the window sash to be swung around to an approximately horizontal position so as to provide minimum obstruction to the ventilating air entering and leaving the building through the open window.

A metal window frame 11 in Figs. 1 and 3 is secured to the masonry or wooden structure 10 of a building with generally U-shaped grooves 12 parallel to and facing each other in the opposite inner vertical walls of the window'frame. Each groove 12 is formed by a removable member 13, removably held in a channel 11a of frame 11 for assembly and disassembly, coacting with the balance of the window frame 11 to form a U-shaped groove, shown as opening toward the right in Fig. 3. I A metal window sash as located within the window frame 11 with this sash being shown at 15 and being preferably made of aluminum or other light-weight material so that the window can be easily pivoted about its horizontal transverse axis. A glass window pane 17 in Fig. 3 is secured thereto in a U-shaped channel within a channel strip 18 of plastic, putty, felt, or any other satisfactory material. The opposite side walls of the U-shaped channel are formed by a projection 15a formed integral with the metal window sash and by an L-shaped member removably secured to the sash 15 by screws 20 to serve as a removable side wall of the U-shaped channel during assembly or removal of the glass window panes 17.

The movement of the lower metal window sash 15 in Figs. 1 and 2 will be first briefly considered. The window sash can slide vertically in the facing U-shaped grooves 12 for raising and lowering the window sash, and the window sash 15 can also be pivoted about its horizontal transverse axis, as shown in Fig. 2. These types of movement are made possible by means located between the window sash and the window frame grooves 12 on opposite sides of the Window sash 15 for slidably and pivotally mounting this sash in the frame. Since both of these means are identical, only one will be described. 7

A window mounting wooden strip member 23 in Figs. 3, 4 and 5 is slidably mounted in its associated U-shaped groove 12 for vertical longitudinal travel. This window mounting strip member 23 is secured to the window sash 15, in a manner to be brought out in more detail later, so that the window sash can be raised and lowered in the window frame 11. Spring pressed rolling means is carried by the window mounting strip member 23 rollingly urged against a portion of the U-shaped groove 12 in Fig. 4 remote from the window sash 15. This means takes the form of two or more rollers 24 with each similarly mounted in recessed portions 23a above and below the vertical center of the strip member 23. Only one is shown in Fig. 4 but all are identical. A one-piece wire spring 25 is bent into proper form from one end 25a extending into a length 25b, a coil 25c around a pin 26 fixed to the member 23 but bridging across the recessed portion 23a, a straight portion 25d, a loop 2512 around one end of the axle of roller 24, and a bail 25 over to the other side of the roller 24 to form a similar and symmetrical structure on the other side of the roller with its end terminating at the first end 25a. It should be readily apparent that this spring 25 normally biases the roller 24 to the left in Fig. 4 against the bottom of the .U-shaped groove 12 since the spring ends 25a bear against sides of the window mounting strip member 23 in'Fig. 3

to provide metal to metal contact with the metal window frame 11 to reduce the wear on the wooden strip member 23 even though it is made of hard maple.

A metal or other type weather strip 29 in Fig. 3 is se- Cured to the Lj-shaped groove or SlQt 12 of the window frame 11 o P v de a W he sea While l din in. e vertical groove or rabbet 23b formed in the window mounting strip member 23.

The window sash 15 is also mounted for pivoting about a horizontal transverse axis in the manner shown inEig. 2. The structure providing this pivoting includes a wooden sash strip 31 secured to the metal window sash 15 by a plurality of spaced screws 32 in Figs. 3 and 4. The window mounting wooden strip member 23 and the wooden sash strip 31 have sealing, contiguous or abutting faces 23c and 31c, respectively, between them, as shown in Figs. 3, 4, 5 and 6. These sealing faces have mating, corrugated or rippled faces with the elements forming the corrugations'being vertical lines. A hearing plate 34, secured by screws to the wooden sash strip 31 in Figs. 3, 4 and 6, iscountersunk into a recess 31:?! into the sealing face 316. A housing plate 35 in Figs. 3 4 and 5 is countersunk into a recess 23d in the sealing face 236 of the window mounting wooden strip member 23. It should be noted that the surfaces of both the bearing plate 34 and housing plate 35, where flush respectively with sealing faces 31c and 230, are correspondingly corrugated to nest with the strips and with each other in a corresponding fashion. A pivot pin 36 extends through aligned holes in bearing plate 34, housing plate 35, and the window mounting strip member 23 in Figs. 3 and 4 to secure the first two mentioned members to the strip member 23. This pin 36 has heads at opposite ends to limit the relative separation of the parts on the pin for a reason to be brought out in more detail hereinafter. it should now be apparent that when the window sash is in the solid line position in Fig. 2, the corrugations on sealing faces 23c and 31c nest together; when the window sashllS is rotated to one of the -dash lin po t on in sthe es he corrugations are forced out of the grooves and bear against the crests of the opposing ridges to thus separate the sealing fac s 3 and 31. t9 th depth f th ee r s tion. The reason for the corrugations will be gone into mor in de ail l ter- .S ep means are p e ir ed o stepping he win 9 indow s sh 1. n y d -dash n e -Q id1 l Jl W-i' tion in Fig. 2. This takes the form of a dogged plate 38in Figs. 3 and v.4 telescoped over pin 36 with this pin extending through a central hole in the dogged plate 3 8. This dogged plate is located between the housing plate .35;and.th e bottom of the recess 2 3d in the window mounting strip member 2 3. A leap spring 39 with a hole through its ,middle, telescoping over the pin 36 in Figs. 3 and 4, resiliently urges .the dogged plate 38 to the right in Figs. 3 and 4 toward the bearing plate 34. The dogged plate 38 has (l ging means, consisting of two spaced dogs 3842, 38a, projecting through aligned holes in the housing plate into doggingcontact with stop portions or detents 34a in Figs. 4 and 6 onthe bearing plate 34. These detents 340 are approximately uniformly arcuately spaced around a circle having a diameter approximately equal vto the distance between dogs 38a, 38a. it should be readily apparent that the dogs, under the bias of the spring 39 will normally seat into diametrically aligned detents 34a but that, rotationofthe window sash 15 will force thelugs out of this space by the camming action between the dogs 38a and the sides of detents 34a against the bias of spring 39 so that the window sash 15 can be readily rotated from one position to the other in Fig. 2 although it will stay located in any given position until a substantial turning forceis exerted.

It should also be noted that the resilient biason springs and 39 .will tend to resiliently urge the corrugated sealing faces 23c and 310 into frictional contact so that the window sash'15 will not turn freely evenin an intermediate position but will'tend to maintain its given position. However, it should be readily apparent that a smaller turning force will move the window sash 15 out of an intermediate position than that required to move it out of one of the dot-dash line or solid line positions in Fig. 2 wherein the dogs 38m and stop detents 34a coact together.

A sealing action exists between the abutting sealing faces 23c and 31C. The interlocked mating corrugations on the sealing faces, when they are pulled laterally together, provide a sealing action. Structure is provided for moving the window mounting wooden strip member 23 in Fig. 3 and its eounterpart on the opposite sideof the window sash 15 toward each other in their respective U-shaped grooves 12 into sealing engagement. The four or more rollers 24 spring-biased by their associated springs 25 not only cause a lateral movement to provide a sealing action but also make easier the lowering and raising of the window sash 15 in the frame 11.

Other structure also helps pull the sealing faces of the strip laterally toward each other to provide sealing. A member 41, having an outer tapered annular surface, has a hole therethrough telescoped over the pivot pin 36in Figs. 3 and and fitting into a socket 34b in the form of afrustu m of a cone with its socket located in the bearing plate 34. It should be noted that there is a keywag "41a extending diametrically across member 41 in Fig. 6. This key-way coincides with and drivingly en gages a key 35a extending diametrically across the housing plate 35 so that no relative rotational movement takes place between the housing plate 35 and the annular member 41 This structure combined with the headed pivot pin 36 will at all times draw and hold together the strips 23 and 31 with the sealing faces 23c and 31c abutting in sealing contact, since the heads on opposite ends of pin 36 limit the relative separation of the parts. The strips will be caused to move laterally together when the weight of the "window sash 15 or the strip 23 causes relativ e v e rtical; longitudinal, or lengthwise movement of the strips 23and 3'1fin Fig. 4 so that the conical or tapered surfaces willcoact like it cam to pull the strips together.

It should be noted that thereis a small space between the tapered smash member 41 and the socket 345 in Fig. 4 so that theridges ofithe corrugations can readily as a a a eef h ar hen the in o is e to one of the dot-dash line positions in Fig. 2. But when the window sash 15 is in the solid line position in Fig. 2 with the corrugations mated together, the weight ofthe Window sash and its glass pane 17 acts through the tapered or conical surfaces to crowd or wedge stfips 23 and 31 together. However, when the window sash is turned to one of the intermediate dot-dash line positions, in Fig. 2, the full bearing surface of the tapered annular member 41 and the cone shape socket 34b coact together to provide a full bearing surface for ease of operation. Even in an intermediate position between any two adi eent ae tiens sh wn in Pie 2 th Weight of h Win sash 1 5 continues to be carried on the tapered and cone shape surfaces so that the strips 23 and 31 continue to be r w era l t he .te s ns a b n i iet b tween the ridges of the corrugations which acts to hold the window sash 15 in any given position of rotation. Then, when the window sash is brought around to the solid line positioninFig. 2, the mating corrugations are drawn together and held tightly by this same structure.

Although the window frame ll' and the window sash 15 aremadeof metal, the window'rnounting strip member 23 and the sash strip 31 are made of hard maple wood. Sash 15 is preferably made of aluminum for lightness and easy manipulation. If metal. were used throughouhit would have to be oil lubricated with this oil drying and tending to gum so as to prevent satisfactory window operation. The corrugated wood sealing faces 23cand 310 are much more satisfactory and will. readily sliprelative to each other after wax or grease has been applied thereto sincethe wax or grease soon permeates the wood and becomes a part of it to proyide a long life of satisfactory operation. Although this metal and wood combination has been the best, it should be understood that other satisfactory material combinations might be used.

It should be noted in Fig. 3 that the window frame 11 and the window sash 15, being made of metal, are designed to protect the wood strips 23 and 31 against the deteriorating effect of the weather. The weather exposed side of this window is the upper edge of the Fig. 3 structure. It should be noted that window frame 11 and the window sash 15 substantially meet at the upper end of section lines 5-5 and 66. Very little of the wood strips 23 and 31 is exposed to the weather. It should be noted that the upper wear strip 28 coacts with the upper side wall of the U-shaped groove and that the metal window sash 15 has a downwardly projecting wall near this exposed portion to limit exposure to a minimum. Also, the Lshaped member 19, used in holding the glass window pane 17 in place, covers and protects from the weather the head of wood screw 32 connecting the window sash 15 and the sash strip 31.

It should now be apparent that this invention relates to a window mounting wherein the window sash 15 is horizontally pivoted on window mounting strip members 23 about its transverse axis for rotation about coaxial pivot pins 36, 36 located on opposite sides of the sash 15 with strip members 23 adapted to be moved laterally inwardly to provide sealing action and to travel longitudinally or vertically in the opposite U-shaped grooves 12 of the window frame 11. The window sash 15 can be readily pivoted about a horizontal transverse axis to any of the positions shown in Fig. 2 or any intermediate position therebetween or completely pivoted to substantially close the window opening so that the glass window pane 17 can be washed on both sides and so that the window can be opened to provide proper ventilation.

Although only lower sash 15 in Figs. 1 and 2 has been described, it should be readily understood that the same structure can be used in the upper sash.

Various changes in details and arrangement of parts can be made by one skilled in the art without departing from the spirit of this invention or the scope of the appended claims.
